Not sure if you're going to have to extend it for use on the 4 door , but I (mildly) doubt it.

Go ahead and also use the Charger's engine bay , engine and TorqueFlite trans . If you want to get even more detailled , make the Charger's diff look like an 9.25" (very similar in appearance to a Dana 44) , as 1974 was the last year for the 8.75" (drop-out carrier) diff .
